Propeller Backpack

The Propeller Backpack is a compact, multipurpose Propeller-based module that is optimized for audio and video applications. Out of the box, and without programming, it serves as a video character display for your BASIC Stamp (or other compatible controller). Using one of our 3-wire Extension Cables you can plug the Backpack into a standard 3-pin servo header and communicate using a simple serial protocol. Any NTSC video monitor plugged into the Backpack’s A/V connector will then display the characters sent by your program in color, in selectable windows, and with selectable character sizes.

The module is also a fully-capable Propeller development platform, which you can program with Parallax’s free Propeller Tool software. Uploading programs to it is a snap, either by using the free LoadBP software via any BASIC Stamp, or directly with the optional Prop Plug (#32201). The Propeller Backpack works in conjunction with your own firmware, or that from the Propeller Object Exchange (OBEX). The Propeller Backpack is expandable, too. The onboard 12-pin socket makes it compatible with Parallax’s complete line of plug-in daughterboards.
